Cause or reason marker

marks a noun as the cause of an event, state, or other result. It is especially natural for concise, factual links involving weather, illness, accidents, noise, and similar circumstances.

How it works

The noun before names the circumstance that brought about the following result. The cause is often outside anyone's control, while the result is usually an event or state such as a cancellation, delay, illness-related absence, or damage.

Common cause-and-result links

Notice that each sentence first gives a noun cause and then reports its consequence.

おおゆきくうこうへいされました。

The airport was closed because of heavy snow.

Analyze

なかさんはこうねつかいけっせきしました。

Mr. Tanaka missed the meeting because of a high fever.

Analyze

こうそくどうじゅうたいしています。

The expressway is congested because of an accident.

Analyze

きんじょこうおとあかちゃんがきてしまった。

The sound of nearby construction woke the baby.

Analyze

Cause versus means

The same particle can mark either a cause or an intentionally chosen means. In the first example, the wind brings about the result. In the second, the scissors are deliberately used to perform the action.

きょうふうまどれました。

The window broke because of the strong wind.

Analyze

Cause: the wind produces the result.

わたしはこのかみはさみでりました。

I cut this paper with scissors.

Analyze

Means: the scissors are a deliberately selected tool.

A neutral factual tone

This pattern reports the causal link without necessarily saying whether the speaker welcomes or dislikes the result. Any positive or negative judgment usually comes from the surrounding words and context.
